Low to no PEC this way.

Hi Theo,

not exactly sure what you mean?. Do you mean setting up
a motor driven wheel while cutting?

Or give away the machining a gear alltogether and steer towards
a friction drive/worm , a la motor driven Alt/Az Dobs?

They too have PEC, the most noticeable being non-concentric worms
and slippage/non concentric friction wheels.

All drive related PEC is measurable and manageable in my Bartels
Stepper drive system. I just rarely have it turned on!

Steve
